Title: Controller for preventing image blur
Inventor: SHIOMI YASUHIKO
IPC: G03B9/08
Filed: 1994-02-03
Abstract: PURPOSE:To prevent a blur detecting means and a flur preventive means from being unsuitably operated by predictively dealing with the generation of estimated factors leading to unsuitable operation of either the blur detecting means or the blur preventive means. CONSTITUTION:The real movement amount of an optical correction system 23 is detected by an optical correction system position detecting means 24, its output is compared with the output of an integrating means 6 by a comparing means, and a differential output between the amount of a blur detected with a blur sensor 5 and the displacement of the optical correction system 23 is amplified. The output of the differentially amplified result is inputted to an optical correction system driving means 25, driving power is supplied from the optical correction system driving means 25 to an optical correction system driving coil so as to eliminate the difference, and the optical correction system 23 is driven by a generated electromagnetic force. In this case, if the output per unit angle to be detected by the blur sensor and the output per unit correction angle of the optical correction system are set equal, a sufficient image blur preventive operation against camera-shakes is performed.

Title: Liquid crystal display
Inventor: TSUTSUMI KUNIHIRO
IPC: G02F1/1345
Filed: 1997-01-07
Abstract: PROBLEM TO BE SOLVED: To provide a liquid crystal display which has no crossover wiring of a LCD electrode and is applicable to chip-on-glass(COG) mounting, by providing it with a controller which reverses displaying bit data of a second LCD forward/backward in relation to displaying bit data of a first LCD and sends the reversed data to a driver. SOLUTION: This device is equipped with a driver 5 which drives a terminal of each electrode in either a first or a second LCD panel 1, 2, and a controller 11 which reverses display bit data of the second LCD 2 forward/backward in relation to display bit data of the first LCD 1 and sends the reversed data to the driver 5. When electrodes driven by the driver 5 are connected mutually from inside to outward, a crossover wiring does not occur in the mutual connection. In addition, because the driven side is opposite from a wiring line 15 which connects symmetrical electrodes each other, the LCD panel can be connected to the electrode without a multi-layer interconnection and a multi-layer board, and the chip-on-glass mounting of the panel is applicable.

Title: Flickering judging circuit of neon lamp
Inventor: KONDO TAKESHI
IPC: G01R31/24
Filed: 1985-01-25
Abstract: PURPOSE:To make it possible to mechanically judge the flickering of a neon lamp, by holding the wave form of the light changing timewise emitted from a neon lamp in a same phase wave form and an inverse phase wave form and comparing the previous level with the present level by using respective two hold circuits. CONSTITUTION:The light of a neon lamp 2 is detected by a light detector 1 and amplifier by an amplifier 3 to be held to hold circuits 4-7. Because the amplifier 3 alternately outputs a same phase wave form and an inverse phase wave form, said light is held to the hold circuits 4, 5 in the same phase wave form and held to the hold circuits 6, 7 in the inverse phase wave form. The difference between the held signal and a present signal is taken by a subtractor 8 and the absolute value of the output from said subtractor 8 is calculated by an absolute value circuit 9 to be given to a comparator 11. The comparator 11 compares the output of the circuit 9 with the flickering level preset to a setting device 10 and, in the case of inferiority, an inferiority judge signal is held to an inferiority judge and hold circuit 12. Because the circuit 12 receives no signal other than the signal in an external signal 13 (measuring period), the output of the circuit 12 is turned OFF when the external signal is turned OFF after the elapse of the measuring period. By this method, the flickering of the neon lamp 2 can be judged.
